SFP transceiver module BlueOptics 551109-BO 1250 Mbit/s Fiber optic

The BlueOptics 551109-BO SFP transceiver module is a compact fiber optic interface designed for 1.25 Gigabit Ethernet links. Engineered for single-mode or multimode fiber networks that require a small form-factor pluggable (SFP) connection, this silver-coloured module supports a maximum data transfer rate of 1250 Mbit/s and a link span up to 20,000 metres. With an MTBF of 1,000,000 hours and compliance with CE, FCC and RoHS standards, the module is intended for stable, standards-compliant optical network deployments and media conversion equipment.

Advantages

The module offers a compact SFP form factor that fits in a wide range of switches, routers and media converters. Its support for 1.25 Gbit/s Ethernet and LC fiber connector enables straightforward integration into existing fiber infrastructures. The silver housing helps with thermal dissipation while the lightweight design (approximately 20 g) simplifies handling and installation. Regulatory compliance ensures compatibility with safety and electromagnetic standards, supporting reliable operation in professional network environments.

Suitable for

• Extending optical links between switches, routers and media converters
• Point-to-point fiber connections over long distances (up to 20 km)
• Replacement or upgrades of SFP ports in network equipment
• Industrial and enterprise networking applications requiring CE/FCC/RoHS-compliant modules

How to use

Install the BlueOptics 551109-BO into an empty SFP port on compatible network equipment until it clicks into place, then connect an LC-terminated fiber cable to the module. Verify link negotiation and speed settings on the host device; the transceiver supports 1.25 Gbit/s operation. For long-distance links, ensure correct fiber type and attenuation budgeting. When removing the module, power down the port if recommended by the equipment manufacturer or follow hot-swap procedures provided by the device vendor.

Recommendations

Use factory-tested LC fiber patch cables and follow fiber handling best practices: avoid tight bends, keep connectors clean with appropriate cleaning tools, and verify link losses with an optical power meter. Confirm compatibility with the host device's SFP firmware and transceiver policy before deployment to ensure stable operation.
